Description
Summary:X‐ray crystal structural data at 100 (2) K for the thallium(I) complex of a fluorinated bis(pyrazolyl)borate, {bis[3,5‐bis(trifluoromethyl)‐1H‐pyrazol‐1‐yl‐κN2]borato}thallium(I), [Tl(C10H4BF12N4)], abbreviated as [H2B{3,5‐(CF3)2pz}2]Tl, and the related tris(pyrazolyl)borate, {tris[3,5‐bis(trifluoromethyl)‐1H‐pyrazol‐1‐yl‐κN2]borato}thallium(I), [Tl(C15H4BF18N6)], abbreviated as [HB{3,5‐(CF3)2pz}3]Tl, are reported. [H2B{3,5‐(CF3)2pz}2]Tl features a two‐coordinate TlI atom with a bent geometry and a boat‐shaped bis(pyrazolyl)borate ligand. It also has several additional inter‐ and intramolecular Tl...H and Tl...F contacts in the solid state. The tris(pyrazolyl)borate analogue [HB{3,5‐(CF3)2pz}3]Tl has a trigonal–pyramidal thallium centre and features inter‐ and intramolecular Tl...F contacts.
